Theresa May is hardly in the shadow of a parliamentary shadow – but now she is in a new jam.
Although it's their arch-opponent Jeremy Corbyn, known for his love of the reserve, the Prime Minister has reportedly told cabinet ministers how to handle the old glasses.
The Daily Mail says it told the Deputies assembled on Downing Street on Tuesday that it is scraping off the mold to go to the lower levels.
A source from Whitehall is quoted as saying the Prime Minister described what was left as "perfectly edible" and encouraged buyers to use "common sense" when it comes to obsolete food.
The tip came during a discussion about reducing food waste.
Her spokesperson later made it clear that it was "a matter for the individual" to follow the practice.
Ms. May has previously given an insight into her culinary taste.
When asked about what she does in her spare time after the 2017 election, she said, "I like cooking, which has an edge, you can eat and do it.
"I have over 150 cookbooks and I spend a lot of time looking at cookbooks."
